@Bodigrim Nice. I assume we need to setup an account with drone.io ? I don't have any access to repo settings, so I won't be able to do anything on that front.

[Bodigrim]

It's already set up.

It seems there is an issue with https://github.com/haskell/random/blob/a390fdee0dab5c661821d343d8d60d3d5ddc2ed9/src/System/Random/Internal.hs#L373-L378 w# is Word64#, so it cannot be an argument of writeWord32Array#, if I'm not mistaken.

Yep, https://cloud.drone.io/haskell/random/1/2/2 fails with

src/System/Random/Internal.hs:377:38: error:
    • Couldn't match expected type ‘Word#’ with actual type ‘Word64#’
    • In the third argument of ‘writeWord32Array#’, namely ‘w#’
      In the first argument of ‘io_’, namely
        ‘(writeWord32Array# mba# i32# w#)’
      In a stmt of a 'do' block: io_ (writeWord32Array# mba# i32# w#)

Beautiful, it is already useful :smile: I'll fix it in a moment

Yep, https://cloud.drone.io/haskell/random/1/2/2 fails with

Fixed and tested in https://github.com/haskell/random/pull/122

Can you also rebase on master and add a badge to readme?

Just replace the whole section with:

| Language | Github Actions | Drone.io | Coveralls |
|:--------:|:--------------:|:--------:|:---------:|
| ![GitHub top language](https://img.shields.io/github/languages/top/haskell/random.svg) | [![Build Status](https://github.com/haskell/random/workflows/random-CI/badge.svg)](https://github.com/haskell/random/actions) | [![Build Status](https://cloud.drone.io/api/badges/haskell/random/status.svg?ref=refs/heads/master)](https://cloud.drone.io/haskell/random/) | [![Coverage Status](https://coveralls.io/repos/github/haskell/random/badge.svg?branch=master)](https://coveralls.io/github/haskell/random?branch=master)

And it'll look like that:

Language	Github Actions	Drone.io	Coveralls

Thanks @Bodigrim I took care of the rest of suggestions that I had
